Abstract

With a development of modern industry, demand for electric power is rapidly increasing and the capacity of power transfer is required to become bigger and bigger. At power station, the high-voltage power cable is used as the only method in order to transfer electric power. In this paper, we have analyzed the deterioration characteristics of 6.6kV power cable systems in operation. For the time duration of 2000 days, we have measured the cable in operation in order to extract the data for the deterioration characteristics. By analyzing the data by means of several steps of filtering processes, we could obtain the linear relations of insulation resistances as a function of time. Furthermore, we can verify that the progress characteristics in deterioration process of 6.6kV power cable systems follows the process of heat deterioration.

현대의 산업이 발전함에 따라 전력에 대한 수요량이 증가하고 송전 용량이 커야할 필요성이 점차 요구되고 있다. 발전소에서는 고전력용 케이블(power cable) 시스템을 유일한 전송 수단으로 사용하여, 생산한 고전압의 전기를 전송한다. 이 논문에서 우리는 활선 상태에서의 6.6kV 전력 케이블에서 발생하고 있는 열화 특성을 연구하였다. 활선 상태에 있는 케이블을 2000일 동안 측정한 데이터를 추출하고 결과에 대하여 수차례의 필터링 과정을 거쳐 분석한 결과, 절연 저항은 시간에 따르는 선형 특성을 나타낸다는 결과를 얻어내었다. 더 나아가서, 6.6kV 전력 케이블이 나타내는 열화 과정이 진행하는 특성은 열열화(heat deterioration) 과정을 따르고 있음을 확인할 수가 있었다.
